6. A properly assembled machine can be seen on
figure E.
Note: When handle knobs are loosened, the handle
can be folded down for storing the machine. En-
sure that the power cable is not caught.
Assembling the grass catcher (Fig. D)
1. Ensure the metal bar frame is pre-assembled
properly into the grass catcher (10).
2. Lift the grass catcher lid (15) and attach the
grass catcher onto the machine (3). Ensure the
holders on the grass box align properly with the
indents of the machine body.
Replacing the blade (Fig. E, G, H)
Disconnect from the mains electricity supply.
Wear strong gloves.
1. Turn the machine (3) on its side and release the
blade retaining clamp (22) by turning the wing
bolt (21) anti-clockwise.
2. Fold the retaining clamp (22) upwards and pull
the blade towards you to lift out the blade drive
socket.
3. To replace, insert blade into drive socket and
other end into blade retaining clamp (22) and
tighten the wing bolt (21) by turning clockwise.
Note: The spring blade (13) must only be used in high-
est three working depths. If you are to use it too deep,
the efficiency will be reduced and spring damage may
occur after prolonged use. The springs are made to
remove the grass and moss from the surface. It is not
necessary to go deeper into the soil. The lowest two
working depths are used for the scarifier blade (12)
for heavier moss removal and scarifying.
4. OPERATION
Always ensure that the machine is in a safe
working condition. Inspect and check safety
devices and guards and check all nuts, bolts
and screws are secure.
Make sure you know how to stop the
machine and ensure you are familiar with
emergency stop.
12
Start the machine following the instructions
and stay clear of the machine's moving
parts.
Adjusting the working depth (Fig. F)
The working depth is adjustable to 5 heights:
-12mm, -9mm, -6mm, -3mm and +10mm.
Be careful not to use the machine at too deep a set-
ting. If there is excessive strain on the motor, it
will lose speed and be less efficient. To adjust the
working depth:
1. Pull the height adjustment lever (20) outwards
(away from the machine housing).
2. Whilst holding the height adjustment lever (20) in
outwards position, push it forward or backward
to the desired working depth.
3. Release the lever (20) and ensure it engaged in
the slot properly.
Securing the power cord (Fig. E, J)
Mount the cable into the cable strain relief (6) as
shown on figure J.
Switching the machine on/off (Fig. E, K)
• To start the machine, press and hold the safety
button (19) and press the on/off switch (18).
Whilst holding the on/off switch (18), you can
release pressure on the safety button (19).
• To stop the machine, release the on/off switch
(18) and wait until cutting blade stops rotating.
Always work your way away from the cables to
avoid cutting them, as shown on figure L.
Using the scarifier blade (Fig. H)
• By scarifying you remove the hardened surface,
grass felt and flat-growing weeds and the crust-
ed over grassroots are loosened up. The lawn
will start to breathe again and assimilate the
nourishing substances, oxygen and water. This
also prevents the establishing of bacteria in the
lawn during the winter.
• Cut the grass to a height of about 40mm before
scarifying. The lawn must be dry when using the
machine. The best time for scarifying is any time
during the vegetative season, from April through
to September. Scarify it at least once a year. We
recommend using a fertilizer straight after airing
if you want a green carpet like lawn.
